The phrase 「ああそっか なんだかこういうのって」 would need to be translated in conjunction with the hand-written 「てれっ = "I feel bashful/flattered/awkward"」, which is used almost like a sound effect or onomatopoeia here though it is originally the colloquial way of saying [照]{て}れる.

The little guy senses the satisfaction on the part of the big guy, which in return gives him a sense of achievement and positive awkwardness.

As in many other cases of J-to-E translations, one would have to use a few words that are not in the original for it to make sense in the target language. My own TL attempt might be something like:

is the use of って here a variant of the quotative って, though here just used to emphasize the self-reflection of the moment? I am familiar with this pattern but only in spoken conversation so I did not know how to define it.

It is originally quotative as a word but here it is used more like a casual topic marker. it is kind of like は but much lighter in feeling. The small っ often makes words sound informal.

Thanks. I had inferred something similar but couldn't find that definition in an online dictionary.
